There are numerous protocols for creating quantum money, [1]}, [2]}, [3]}, [4]} to name a few.
In fact, the very first cryptographic task using quantum information was a money scheme in Wiesner's seminal paper [1]}.
The key idea behind Wiesner's protocol, and those that followed, is that quantum theory could promise security based on the impossibility of cloning an unknown quantum state, and not on any technological limitations.
In other words, security based on the laws of physics rather than the limited resources of the counterfeiters.
